GLA700-2 12V DC 700N Compact Linear Actuator

The GLA700-2 offers the build quality of higher-cost actuators at an affordable price, with a small body size ideal for providing electrical automation in tight spaces. The operating voltage of 12V DC makes it suitable for powering from a standard lead-acid battery, or running from a mains to 12V DC adapter such as our own high-efficiency 8A model.

The shallow lead-angle of this actuator (with a 3.175mm pitch, single-start screw) means that if the actuator is driven into a position it will tend to stay in that position unless power is applied once again, or unless it is subjected to a load larger than the rated load.  

The outer enclosure features O-ring seals under every screw head as well as gaskets at each seam and a sturdy wiper ring about the extending rod. This design adds up to an IP66 enclosure rating, suitable for most external use. Bear in mind that the actuator should not be submerged in water, or exposed to continuous running water. If mounting outdoors it is best to orient the extending rod tilted downwards, so that water tends to run away from the moving seal between rod and body.

Please bear in mind that, with its all-metal spur gear transmission, this actuator model is not intended to be especially low-noise by design. If your design requires low-noise actuators please look at the GLA1500-N or GLA800-N models, or ask us for advice on other alternatives. 

The actuator comes with a 0.8m PVC insulated lead as standard (grey external sleeve with two internal copper cores, one red and one black) with bare tinned lead ends. An option is provided for a DC (barrel type) power connector to be added (2.1mm internal diameter, 5.5mm external) on a 300mm lead, bringing the total lead length to 1.1m. Allow for one extra working day to process your order if a connector option is added, since these are soldered and insulated to-order.

We are able to supply custom wiring and connectors upon request, please contact us with your requirements if interested.

User Advice

To change the direction of travel simply swap the polarity of the DC power source to the two actuator leads (this may be achieved using hardware such as our rocker switch harness or GLA-CU-X3 remote control unit). By varying the input voltage between 0-12V DC it is possible to control the speed of the actuator. Reducing the voltage will also reduce load capacity (for example at 6V the actuator will have roughly half of the maximum load capacity at 12V).

This actuator is designed primarily for compression loads, it will typically work OK in tension, up to the same rated maximum load, but can be more susceptible to damage from overloading. Shock loads through the mounting points should be avoided.

As with any DC motor the motor may be run at a higher voltage than the nominal 12V DC however operation at higher voltages will invalidate the warranty. Experienced users who wish to extract greater power from the actuator (at their own risk) should abide by a practical operation ceiling of 18V, above which the motor, diodes and limit switches of the actuator would be significantly more likely to fail. Be aware that the current draw will be greater if the actuator is run at above 12V DC and the duty cycle should be reduced to help avoid over-heating.

Ensure that the control hardware and power source are capable of providing sufficient current for the loads you expect the actuator to experience. We cannot be held liable for damage caused to connected hardware due to inappropriate hardware selection. 

CAD models (STEP, IGS, Autodesk Fusion 360) of the actuator are available upon request. Contact us with the size(s) and file formats that you require and we'll attach the files in return.

Operating Characteristics

Actuator Build Detail

Size: (click on image to expand)
Installation length:	This is the distance from the front to rear mounting hole centres when the actuator is retracted. 50mm stroke: 155mm 100mm stroke: 205mm 150mm stroke: 255mm 200mm stroke: 305mm 300mm stroke: 420mm Add the stroke length to the installation length to get the fully extended hole-to-hole centre distance (for example this distance would be 305mm for the 100mm stroke).
Mounting:	Two ~6.5mm diameter through-holes. One is towards the end of the piston rod, the other is on the rear of the gearbox housing.
Body material:	Aluminium & painted steel, rated to IP66.
Certification:
Operating temperature:	-15°C ~ +45°C
Gearbox type:	Four-stage spur gear reduction (all-metal gears). Total reduction ratio 21.14:1 (4sf). Made up of first stage (Teeth:Teeth) 26:14, second 27:17, third 43:12 and fourth 38:19.
Lead screw:	Single-start steel screw, 3.175mm pitch.
Limit switches:	Two limit switches are installed at the ends of travel which automatically stop travel at the fully retracted and extended positions. The internal circuit is as pictured below (click on image to expand):
Wire length:	0.8m, excluding optional DC connector cable which brings the total length to ~1.1m.
